Cut the meatloaf, potatoes and carrots into small cubes. Chop the onion very finely or mince it with a magic wand.
In a saucepan, sauté the meatballs with the onions in oil until the onions are translucent. Add the potato pieces to the pot and fry well. Possibly add a spoonful of oil while stirring constantly. After about 5 minutes the potatoes have a light roasted aroma. Top up with water until the potatoes are evenly covered.
Add the ham cubes, marjoram, thyme, salt and pepper. Simmer on a low heat with the lid on for about 20 minutes. Grate some nutmeg on top. Mash the potatoes with a pounder so that only small pieces are left. This gives you a fine consistency, but the soup does not turn glassy.
If you like, add sliced sausages and leave to stand for 2-3 minutes before serving.
